A mum of three lost seven stone in a year after seeing photos of herself on a bouncy castle at her son’s birthday party.
Kirsty Fowler, 33, of Baker Street, Waddesdon, weighed 17 stone at her son Callum’s seventh birthday party.
But now, at 10 stone, she has been asked to be a diet counsellor to help others with their weight loss.
Kirsty said: “I wasn’t sure what was bigger, the bouncy castle, or me!
“I looked at myself and thought that is disgusting. How can I be a role model to my children if I am sat there stuffing my face? I looked like a beached whale.” Kirsty, who used the Cambridge Diet of bars and shakes to lose weight, is currently tutoring nine Aylesbury people to try and do the same.
Along with the photo, Kirsty was motivated by the death of her 35-year-old sister Annette from cancer in 2006.
Kirsty, who takes part in the Race for Life charity run in memory of her sister each year, said she ate to deal with the loss.
Kirsty said: “I was depressed, siting on my backside, watching too much TV.
“Some people turn to alcohol, I turned to food.
“But she always used to hassle me about my weight so I had her in my head, spurring me on.”
